Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic file device that stores image information in a storage device and retrieves and outputs a necessary image from the stored image information. The present invention relates to an electronic file device with an image editing function capable of correcting and additionally writing stored image information using image patterns such as characters and symbols. [Prior art] A conventional electronic file device with an image editing function is disclosed in
As described in Japanese Unexamined Patent Publication No. 26035, when performing editing processing of image information, the original image information is read from a storage device, information such as characters and symbols is added to the original image information, and the processed image information is added. Is re-registered in the recording device. Normally, in the editing process involving this correction, the corrected part of the original image is replaced by a new correction, so when searching and displaying the corrected image information, it is not possible to recognize which part has been additionally written. It is not possible to restore the image information to the state before the additional writing. [Problems to be Solved by the Invention] Generally, in a document processing, when a registered text or figure is additionally corrected, a part of the registered text that is additionally corrected is deleted and additional information is entered. Have been. However, this deleted or added information may contain important information for the creator, processor, and reader of the text, so that both information can be understood without deleting the original information. It is widely performed to add a diagonal line or the like and write new information in the vicinity thereof. Further, a red underline may be added to clarify an important part in the text, or a comment may be added in a blank space of the document in red. This is to make it clear that the information is added to the original information. As described above, when a document is modified or added, it is extremely important to identify where the corrected or added portion is located. In the prior art, no consideration is given to identifying the corrected / additionally added portion, and even if the image after the correction / additional entry process is displayed, any portion of the corrected / added image information is displayed. There was a problem that it was not possible to identify whether it was. [Object of the Invention] An object of the present invention is information in which correction / additional entry can be made to original image information, and in which part data is modified / additional to the original image information. It is an object of the present invention to provide an electronic file device which can easily identify the above on an image display means. Still another object of the present invention is to provide an electronic file device capable of displaying image information in color on an image display means and performing processing such as redlining correction on the original image information and addition of redlining underlining. Is to do. [Means and Actions for Solving the Problems] An object of the present invention is to provide an electronic file device with an image editing function, comprising: a first buffer memory for temporarily storing original image information as first image information; Image creating means for adding and modifying information to create second image information, a second buffer memory for temporarily storing additional image information created by the image creating means, first and second This is achieved by providing image display control means for synchronously reading out the two pieces of image information stored in the buffer memory and displaying the image information on an image display means such as a CRT. That is, the original image information is temporarily stored in the first buffer memory, and the contents of this memory are not added or modified at all. All additional image information newly created by adding / modifying the original image information is temporarily stored in the second buffer memory. Then, the image display means combines and displays the two pieces of image information as if they were added or corrected to the original image information. Also, when performing the combined display, the images are displayed in different colors, for example, so that the two pieces of image information can be identified. This makes it clear at a glance the portion added or corrected to the original image information, and enables redline correction of the text, addition of an underline, and the like. Note that the image information temporarily stored in the first and second buffer memories is also stored in separate areas when storing the image information in the image storage unit. Therefore, it is also possible to read both image information separately from the image storage means, and it is possible to perform image display of only the original image information and image display of only the additional image information even after being temporarily stored in the image storage means.

The image memory 13 includes a work image memory 10, an original image memory 11, and a postscript image memory 12, and temporarily stores image information supplied from an image data bus 16. Each of the memories 10 to 12 can store image information for one screen on the CRT 15.
The work image memory 10 is used as a work area for arbitrarily combining the image information of the original image memory 11 and the postscript image memory 12 when outputting the image information from the image output device 7. The original image memory 11 receives the initially input image information, and the additional image memory 12 stores the added / modified input image information. Here, in the original image memory 11 and the additional image memory 12, one pixel is set to "1" (black pixel), "0".
A monochrome image expressed by binary data of (white pixels) is stored. The pattern generator 9 generates an image and a graphic pattern such as a character, a symbol, a straight line, and a curve according to an instruction from the main control unit 3. These patterns are additionally written into the additional image memory 12 in the image memory 13 via the image data bus 16. The CRT display control unit 14 combines each image information in an arbitrary combination,
This controls output in an arbitrary color. That is, the color register control signal group 17 is received from the main control unit 3,

Then, the two image data 19 and 20 are combined, and the image information is represented by three signals of R (red), G (green) and B (blue) (hereinafter simply referred to as “RGB”),
The display image data 21 is created. Also, the CRT display control unit 14
Receives the cursor control signal group 18 from the main control unit 3,
The cursor image is superimposed on the display image data 21. This makes it possible to display a cursor at an arbitrary position on the CRT 15. The CRT 15 is, for example, a color CRT display, and receives the display image data 21 so that the original image memory 11,
The color image synthesized from the monochrome image information of the two surfaces on the postscript image memory is displayed on the CRT 15. Next, the internal configuration of the CRT display control unit 14 will be described in detail with reference to FIG. FIG. 2 is a block diagram showing the internal configuration of the CRT display control unit 14. The color register 26 includes four registers, a register 22, a register 23, a register 24, and a register 25. Each register holds RGB 3-bit data for color display. The selector 27 is a selector for selecting and outputting each of the register outputs 32 to 35 in accordance with the presence or absence of the original image data 19 and the postscript image data 20.
The cursor generator 37 generates a signal for displaying a cursor in a designated area of the CRT 15.
Numeral 38 is for synthesizing and displaying the selector output 36 as image information and the cursor output data 39 as cursor information. Next, the operation of the CRT display control unit 14 will be described. The data setting to the color register 26 is performed by the main control unit 3 via the color register control signal group 17. The color register control signal group 17 includes a register set signal 40 and a register input 28, a register input 29, a register input 30, and a register input 31, and each of the register input signals 28 to 31
Is composed of three RGB signal lines. The main controller 3 outputs RGB data to be set in each register to each register input signal, and issues a register set signal 40. As a result, each RGB signal is set in each of the registers 22 to 25. Here, the RGB data set in each of the registers 22 to 25 is shown in FIG. In FIG. 3, the RGB data set in the register 22 corresponds to white display, the RGB data set in the registers 23 and 25 correspond to red display, and the RGB data set in the register 24 corresponds to black display. Become. In FIG. 2, the output signal of each register is output as a register output 32, a register output 33, a register output 34, and a register output 35 through three RGB signal lines.
The selector 27 selects each of the register outputs 32 to 35 which are the input signals of the selector 27 according to the presence / absence of the data of the original image data 19 and the postscript image data 20, and outputs it as a selector output 36. The selector output 36 is composed of three RGB signal lines. Here, the operation of the selector 27 will be described with reference to FIG. FIG. 4 is a functional diagram of the selector 27. Here, “0” in the original image data 19 indicates that the original image information is a “white” image, and “1” indicates that the image is a black image. In addition, “0” of the additionally written image data 20 indicates that the corresponding pixel of the additionally written image is a pixel to which no additional writing has been performed. Original image data 19 is “0”
When the additional image data 20 is “0”, the data of the register output 32 is selected as the selector output 36, and the display color on the CRT 15 is white. Similarly, a register is selected based on the original image data 19 and the additional image data 20 as shown in FIG. 4, and the display color on the CRT is determined. Description will be made again with reference to FIG. The selector output 36 is input to the cursor synthesizer 38. The cursor generator 37 has
The cursor display position information and the cursor display color information are given from the main control unit 3 via the cursor control signal group 18.
The cursor generator 37 turns on the cursor output control signal 47 in response to an instruction from the main controller 3 and outputs an RGB signal corresponding to the cursor display color as the cursor output data 39.
The cursor synthesizer 38 is controlled by a cursor output control signal 47, and outputs the cursor output data 39 as the display image data 21 when the cursor output control signal 47 is ON. When the cursor output control signal 47 is OFF, the selector output 3
6 is output as display image data 21. Display image data 2
1 is also composed of three RGB signal lines. As is clear from the above description, the color register 26,
By the operation of the selector 27, the image information on the original image memory 11 is displayed on the CRT 15 as a "black" image on a "white" background. The postscript image information in the postscript image memory 12 becomes a "red" image on a "white" background, and is synthesized and displayed on the "black" original image on the "white" background. Further, when the original image data is “1” and the postscript image data is “1”, the display color on the CRT 15 is red,
At the pixel where the black display of the original image information and the red display of the additional image information collide, the additional image information is preferentially displayed. The overall configuration of the present embodiment has been described above.
With reference to the drawings, a procedure and an operation of each unit when redlining correction processing is performed by the apparatus of the present embodiment will be described. FIG. 5 is a diagram for explaining the original image information stored in the original image memory 11, the additional image information stored in the additional image memory 12, and the display screen of the CRT 15 in the redline correction process. Hereinafter, redline correction processing is performed on the original image information retrieved and read from the image storage device 8, and
The procedure of the process of storing the data in the storage device will be described. (1) The operator uses the keyboard 4 to set the apparatus in an image search mode. Next, when the index information of the search target image is input from the keyboard 4 and an instruction to read the image is issued, the original image information of the target image is read from the image storage device 8 and stored in the original image memory 11. Further, in the present embodiment, since the additional writing process has not been performed yet, the additional writing image information in the additional writing image memory 12 is a blank image (all “white” images). The contents of the original image information, additional image information, and CRT display screen at this stage are shown in STEP 1 of FIG. (2) The operator uses the keyboard 4 to set the apparatus in the image additional recording mode. Next, a straight line drawing instruction is issued from the keyboard 4. Then, using the pointing device 5,
The cursor 40 is positioned at the left end point where direct drawing is to be performed, and the cursor 41 is positioned at the right end point. (STEP 2) (3) When a process execution instruction is issued from the keyboard 4, the main control unit 3 executes coordinate calculation of both ends of the straight line indicated by the cursor 40 and the cursor 41, and issues a straight line drawing instruction to the pattern generator 9. Soup The pattern generator 9 generates the specified linear pattern on the postscript image information. Then, the straight line image 42 is written in the additional image memory 12, and the corresponding portion of the straight line image 42 is displayed in red on the CRT display screen, and
43 occurs. (STEP3) (4) Next, the process proceeds to the input of a character string for image correction from the keyboard 4. Prior to this, use the pointing device 5 to move the cursor 40 to the upper left point of the area where the character string is to be input.
Is positioned at the lower right point. In the state where the character string input is instructed, after the cursor 41 is set, the cursor 40 and the rectangular cursor 44 defined by the cursor 41 are changed to CR.
Displayed on the T display screen. (STEP 4) (5) Next, when the operator inputs the corrected character string from the keyboard 4, the main control unit 3 calculates the position coordinates of the rectangular area indicated by the cursor 40 and the cursor 41, and generates the pattern generator. 9 to issue a character string embedding instruction. The pattern generator 9 generates the designated character string pattern, and this pattern is written in the postscript image memory 12. The input character pattern 45 is written on the postscript image memory 12, and the CR
The corresponding portion of the input character pattern 45 is displayed in red as a red character string 46 on the T display screen. (STEP5) (6) When the character string input termination is instructed from the keyboard 4, the rectangular cursor disappears from the CRT display screen. The character string "ABCD" of the original image information is crossed out by the red line 43, and the red character string 46 "EFGH" is displayed below the line, and the red line correction process is completed. (Step 6) (7) Here, when an image update registration instruction is issued from the keyboard 4, the additional image information in the additional image memory 12 is transferred to the image storage device 8 and updated and registered. Here, in the above operation, since the original image information in the original image memory 11 is not modified at all, there is no need to update and register the original image information in the image storage device 8. (8) After executing the redline correction processing of (1) to (7) above, if the image search mode is selected again and the reading of the above-mentioned image is instructed, the target image after the redline correction processing, that is, the original image information and The additional image information is read from the image storage device 8 and stored in the original image memory 11 and the additional image memory 12. At this time, the contents of the original image information, the additional image information, and the CRT display screen are the same as in STEP 6 in FIG. (9) When the additional image display stop is executed in accordance with an instruction from the keyboard 4, only the original image information is displayed on the CRT display screen. Therefore, the above (1) to (7)
No matter what addition or correction is made to the image information, the original image information can always be confirmed according to the procedure described in (1). Here, a method of stopping the display of the postscript image will be described. Stopping the display of the postscript image can be easily realized by updating the contents of the color register 26 in FIG. FIG. 6 shows the contents of the color register 26 when the additional image display is stopped. The function of the selector 27 at this time is as shown in FIG. 7, and the display color on the CRT display screen is determined only by the original image data. By updating the content of the color register to another value, CRT display of only the additional image information is possible, and display colors of the original image information and the additional image information on the CRT display screen can be changed. (10) In the redline correction processing described above, only the additional writing of image data and graphic patterns to the additionally written image information has been described. However, when such an image is processed, the already added image pattern is corrected, added, or deleted. Sometimes you want to. In this case, a blank image (“white” image) is generated by the pattern generator 9, and the blank image is written in the additionally-written image memory 12 so that the entire or partially-cleared additionally-written image memory 12 can be cleared. And the above (2)
Additional writing is performed in the same procedure as in (7). The redline correction process is performed by the above procedure. If the cursor 40 and the cursor 41 in the procedure (2) are positioned below the character string "ABCD" on the original image information, the procedure (3) is performed. , The underlining of red is added. Also, if only steps (4) to (6) of the above procedure are executed, red text is added to the original image information. Further, image information input from the image input device 6 or image information read from the image storage device 8 can be stored in the additional image memory 12 as an additional image. Next, an operation of printing an image displayed on the CRT 15 by the image output device 7 will be described. The image information on this apparatus is expressed by two pieces of image information of the original image information and the postscript image information. Therefore, in order to output an image to the image output device 7 which outputs a monochrome image, the above-mentioned 2
It is necessary to combine the image information of the planes. In the present embodiment, this synthesis processing is executed by the main control unit 3. When outputting the image information of the two surfaces stored in the original image memory 11 and the postscript image memory 12, the main control unit 3 writes out the contents of both memories 11, 12 and executes an OR process. The image information is stored in the work image memory 10.
Next, the work image memory is instructed by the main control unit 3.
The image information of 10 is output by the image output device 7. Further, in the present embodiment, it is also possible to select the output of only the original image information or the output of only the postscript image information according to an instruction from the keyboard 4. In this case, only the image information from the original image memory 11 or the additional image memory 12 is output by the image output device 7. As described above, according to the present embodiment, processing such as redline correction processing, redline underlining addition, redline text addition, and the like can be performed on the electronic file device. Also, any modification or addition of a sentence or the like is processed as postscript image information without any processing on the original image information, and is stored in the image storage device 8 separately from the original image information. This makes it possible to confirm the additional image information. Note that various modifications can be made as follows, for example, without departing from the gist of the present invention. (1) In the above embodiment, the CRT 15 is described as a color CRT, but the display unit may be a monochrome CRT. In this case, of the RGB3 signals constituting the display image data, only the G signal is given to the monochrome CRT. As is clear from the data column of the G signal in the selector function table of FIG. 4, when the original image data and the additional image data are (0, 0),
The signal given to the monochrome CRT is “1” (display color “white”)
In the case of (0,1), (1,0), (1,1), the value is "0" (display color "black"). That is, the original image information and the additional image information are OR-combined and displayed on the display screen. Here, if the values of the registers 22 to 25 are rewritten as shown in FIG.
As shown in the G data column in FIG. 7, when the original image data is “0”, the signal applied to the monochrome CRT is “1” (display color “white”), and when the original image data is “1”, Monochrome
The signal to the CRT is "0" (display color "black"). That is, only the original image information is displayed on the display screen. If the values of the registers 22 to 25 are corrected, only the additional image information can be displayed. (2) When combining and displaying original image information and postscript image information when using a monochrome CRT, change the luminance of the postscript image, make it reverse characters, shade, or blink to distinguish the two information. It is possible to take measures such as causing To perform luminance modulation on a monochrome CRT, for example, R.G2 data in the display image data 21 is given to the monochrome CRT, and when RG is (1, 1), low luminance (“black display”) is set.
In the case of (0,0), normal brightness ("white" display) and (1,0)
In the case of (1), this can be achieved by operating the CRT with high luminance (bright "white" display). [Effects of the Invention] As is clear from the above description, according to the present invention, correction processing of image information, addition of underline, addition of text, deletion of text, and the like can be easily performed on the electronic file device.
Further, it becomes clear at a glance which part has been added or corrected to the original image, so that an extremely remarkable effect that the original image and the added image can be confirmed forever can be obtained.
